- Thermal Noise Analysis in ECG ApplicationsPDF, 114 Kb, Archivo publicado: mayo 3, 2011
This article discusses the thermal noise source of electrocardiogram (ECG) applications basedon the ADS1298 and ADS1298R family of multichannel, simultaneous sampling, 24-bit, delta-sigma (О”ОЈ) analog-to-digital converters (ADCs). This report offers several observations on identifying the major sources of thermal noise in an ECG system, and makes several recommendations regarding how to improve t - Improving Common-Mode Rejection Using the Right-Leg Drive AmplifierPDF, 297 Kb, Archivo publicado: jul 6, 2011
This article discusses the need to improve common-mode rejection (CMR) in electrocardiogram (ECG) subsystem applications. Several different techniques to improve CMR while also considering both patient and operator safety are presented. This report also reviews the implementation of the right-leg drive (RLD) loop technique to improve CMR using the ADS129x family of analog-to-digital converters (in - Analog Front-End Design for ECG Systems Using Delta-Sigma ADCs (Rev. A)PDF, 191 Kb, Revisión: A, Archivo publicado: abr 13, 2010
This document discusses the characteristics of electrocardiogram (ECG) signals and different front-endapproaches for ECG signal acquisition. The tradeoffs between different approaches and the effects on overall system design are discussed. The report also includes descriptions of potential implementations of the front-end architecture using the ADS1258 and ADS1278 and respective noise measuremen - Analog-to-Digital Converter Grounding Practices Affect System Performance (Rev.
